Sequence Manipulation Suite v0.4.39

SMS3 v0.4.39

Feature mouseovers stay inside the visible viewer panel, including smaller
scrolling containers, instead of extending below it and introducing scrollbars
that make the view jump. Long annotation cards scroll internally and open inward
when close to an edge.

The shared positioning fix covers Canvas and SVG inspection, including linear
DNA, circular DNA and protein viewers and their standalone HTML exports.
Annotation text, feature colours and scientific coordinates are preserved.

Release tests, local browser gates and live browser smoke tests are intentionally
skipped at the maintainer's request. The tooltip fix was verified before this
release request; no tests were rerun for publication.
